• Direct designer of several projects for Flex-N-Gate , Cascade, Stackpole, Linamar…etc. companies in terms of structure, tooling, guarding and conveyer and gantry.
• Performs FEA study on machines’ structure to estimate deflection, FOS ( Factor of Safety), VonMisses stress, and Maximum allowance load and pressure. 
• Prototyping machine’s components by 3D printer to evaluate their functionality at service.
• Calculates required force , torque, air & oil pressure in order to select appropriate material, pump, tank and compressor as well FOS( Factor of Safety) estimation.
• Simulates and modifies robots’ range of motion to avoid any interference and collision with other machine’s members.
• Manages and follows up lead time projects’ components as well as sending RFQs and POs.
• Communicates closely with clients to accommodate their needs , safety matters and ergonomics for machines’ operators to reach final design approval.
• Creates BOM, manual, spare parts list by utilizing SolidWorks and Questica.
• Calculates cost estimation of manufacturing processes including Machining, Waterjet, Laser bending.

• Performed overhaul, scheduled, corrective and preventive maintenance for manufacturing line to assure production line working uninterruptedly.
• Followed manuals, manufacturer's instructions, engineering specifications for boilers, generators, pumps, hydraulic & pneumatic machines, Jacks, batching, labeling and filling machines.
• Utilized reverse engineering procedures to troubleshoot the machines’ malfunctions.
• Carried out scheduled maintenance log sheet along with ordering spare parts for mentioned machines to not face any deficiency to keep pace with production line.
• Cooperated and communicated with machines’ manufacturers and suppliers mainly overseas, with WebEx, Skype, WeChat, WhatsApp, and video call, to troubleshoot machines to resume production line in initial optimal condition and reduce maintenance cost and time. 
• Improved efficiency by substituting machines’ original parts with more durable and long-lasting parts comprising bearing, O-Ring, gasket, shaft, high-pressure hose, and connector. 

• Executed design for a variety of Thick-Walled Cylindrical Pressure Vessel CNG Tanks for vehicles powered by gas, ranging from 28 Liter to 75 Liter based on ISO 11439 and INSO.
• Evaluated DFMEA by utilizing FEA methods to examine failures in terms of Fatigue, Statics, Impact, and burst to assure about meeting standard requirements and FOS (Factor of Safety).
• Involved in all stages of design comprising Sketch, Drawing, datasheet, sheet format, 3D Modeling, GD&T and BOM.
• Prepares mathematical models, followed mesh study and refinery procedures to reach a reasonable mesh intensity & type in SolidWorks and ANSYS then validate simulated results.
• Constructed sheet metal design for tank mounting brackets to minimize waste of raw material.
